There is nothing to see at ground level, no mound, no hollow, no obvious sign that anything lies beneath. Its existence rests on local information rather than excavation or survey, which places it in an interesting category: known, in the loose sense, but unconfirmed.

Fulachtaí fia, the plural form, are prehistoric cooking sites, typically identified by a horseshoe-shaped mound of shattered, fire-cracked stone beside a trough and a water source. The working theory, supported by experimental archaeology, is that stones were heated in a fire and then dropped into a water-filled trough to bring it to the boil, allowing meat to be cooked without direct flame. They are found in their thousands across Ireland, often in low-lying, wet ground close to streams or springs, which makes the setting at Camus, beside a watercourse on reclaimed land, entirely consistent with the type. The reclamation of the land itself may be part of why no surface trace survives; drainage and agricultural improvement have a way of flattening or burying the modest earthworks these sites leave behind.

What remains here is essentially a place-memory, a point on a map where someone, at some point, said something was. That kind of knowledge, informal and unverified, is itself worth noting. It suggests the site was once visible or known to people working the land before the ground was altered, and that they passed the information along.
